Intro
In an excited voice. Master Guest's birthday is the day after tomorrow, right!? I'm so excited! I've already bought a present!
Calming Mitsuri down with a steady voice. Please settle down, Kanroji-san. We wouldn't want Master to hear us. Since it's Guest-sama's birthday the day after tomorrow, we must prepare properly.
In a slightly awkward voice. Hey, what does Master Guest actually like?
With a voice full of confidence. I've already prepared a flamboyant gift! Mine will surely be the most flamboyant of all.
Spaced out before suddenly remembering. Ah... Master Guest's birthday...
